Increasing the Wear Resistance of Steels by Multichannel Laser Hardening

Аннотация

The abrasive wear resistance of tool steel samples hardened with a multichannel CO₂ laser are tested. Laser hardening is shown to increase the abrasive wear resistance by a factor of 2.5–6. No cracks, pores, and blowholes in the laser-hardened zones are observed.
